[Core Advantages]
1. Dual core turbocharging technology (patent number CN2022XXXXXX)
-Adopting a stepped dual cylinder linkage structure, the measured single impact air pressure fluctuation value is ≤ 0.15MPa (industry standard 0.3MPa)
-The penetration efficiency of granite layers has increased by 37% compared to traditional models
2. Intelligent thermal management system
-The three-stage oil cooling circulation device keeps the temperature of the core components constant at 65 ± 3 ℃ (measured data at an ambient temperature of 50 ℃)
-No power attenuation record for 72 hours of continuous operation
3. Modular maintenance design
-Quick detachable filter element can be replaced in 3 minutes (requires a special tool kit)
-Key sensors adopt military grade IP69K protection standard
